地理现象时空分布规律归类小结（Geographical phenomena, temporal and spatial distribution, classification, summary） Geographical phenomena, temporal and spatial distribution, classification, summary Geographical phenomena, spatial distribution, temporal distribution Winter, half a year, summer, half a year The rotation of the earth spins on its axis to form the equatorial plane, rotation speed from the equator to the poles through the axis of the Arctic back to the sun, the northern hemisphere is less across the Arctic axis toward the sun, the Northern Hemisphere The area is much heated The formation of the orbit of earths surface (Huang Dao), the sun a focus in a nearly circular orbit last month at perihelion, the earth revolution velocity, line speed, winter is short at the beginning of July, the earth revolution speed near aphelion, Line speed is slowest, summer half a year is longer From the height of the sun at noon sun point to the north and south sides. Around December 22nd, the tropic area to the south of the northern hemisphere equator and reached the maximum, reached the minimum around June 22nd, the north of the Tropic of cancer area reached the maximum, the equatorial and southern hemisphere reached the minimum The solar terminator line height is zero, the world is divided into two diurnal hemisphere, atmospheric scattering leads to large range of actual day hemisphere hemisphere midnight; with the rotation of the earth, the morning line westward, faint line eastward the northern hemisphere morning line and West partial increases with latitude, faint line with latitude increasing East Northern hemisphere the morning line increases with latitude East, with faint line The latitude increases and the West slants The length of day and night the sun which hemisphere, which is hemisphere day long, and the higher the latitude day longer the Arctic circle appears very day Short day and long night, night appears within the Arctic Circle Sunrise position, the sun always rises East
